The answer to why salting up sweets is such a genius idea lies in your tastebuds. A study by Okayama University found that the chloride in salt activates sweet taste receptors.

Chloride is also believed to interact with a certain taste receptor associated with sweet foods, which sends signals to your brain that react as if you've eaten something sweet.
